Customer proprietary network information

Customer Proprietary Network Information (CPNI) is the data collected by telecommunications companies about a consumer's telephone calls. It includes the time, date, duration and destination number of each call, the type of network a consumer subscribes to, and any other information that appears on the consumer's telephone bill.

Telemarketers working on behalf of telephone companies, attempting to either win back a customer or upsell a customer with more services, must ask the customer's consent before accessing the billing information or before using that information to offer an upsell or any change of services. Usually this is done at the beginning of a call from the telemarketer to the telephone subscriber.

The U.S. Telecommunications Act of 1996 granted the Federal Communications Commission (FCC) authority to regulate how customer proprietary network information (CPNI) can be used and to enforce related consumer information privacy provisions. The rules in the 2007 FCC CPNI Order further restrict CPNI use and create new notification and reporting requirements.

The rules in the 2007 CPNI Order include:

Note that as long as an affiliate is "communications" related, the FCC has ruled that CPNI is under an opt-out approach (can be shared without your explicit permission). A phone company is permitted to sell all information on you, such as numbers you call, when you called them, where you were when you called them, or any other personally identifying information. CPNI would normally require a warrant for law enforcement agencies, but it can be freely sold to "communications" related companies. One can verify this by checking rule 64.2007(b)(1) and footnote 137 in the 2007 CPNI order. One can call up a phone company and opt out by requesting that they do not share CPNI information. In the case of Verizon Wireless, for example, the company states that on the one hand, "Your privacy is an important priority at Verizon Wireless", and on the other hand, states that Verizon shares CPNI "among our affiliates and parent companies (including Vodafone) and their subsidiaries unless you advise us not to". and states that it shares "URLs (such as search terms) of websites you visit when you use our wireless service, the location of your device ("location information"), and your use of applications and features" as well as other "information about your use of Verizon products and services (such as data and calling features, device type, and amount of use), as well as demographic and interest categories (such as gender, age range, sports fan, frequent diner, or pet owner)" with other non-affiliated companies, and does allow customers to request that such sharing not be done via an online form, and it is unclear whether Verizon considers some or all such "online" requests to be about CPNI or as legally binding as "call-based" requests about CPNI.
